The fast spreading MyDoom computer virus has planted little data time bombs in tens of thousands of computers, set to send a flood of traffic Sunday.
The mechanism left behind in infected computers is timed to unleash a flood of messages in two directions after midnight, with the main blast directed at SCO Group, a company that has raised the ire of Linux enthusiasts by filing legal actions to claim parts of the supposedly public domain code.
SCO has already been mostly isolated by its Internet suppliers to cut down on millions of messages directed there, as many as one in every 12 E-mails by one count earlier in the week, CNET News reported.
The other target, of a variant named MyDoom B, is Microsoft's Web sites.
It is possible, however, that virtually everyone using the Internet Sunday will see the effects of the twin denial-of-service attacks, as E-mail pathways become clogged with bogus messages and the traffic load slows Internet operations in many parts of the world.
Many free downloads that remove MyDoom from individual machines are available via the most popular search engines.
